[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device used for a garden staging light or the like.

[0002]

2. Description of the Related Art FIG. 3 shows an external view of a conventional lighting fixture used for a garden plant light or the like. FIG. 4 shows the configuration of the main part. In this conventional lighting apparatus, a light-transmitting plate 11 made of a glass plate or the like is installed on the ground 4 via an arm 3 and an upper portion of the light-transmitting plate 1 as shown in FIG.
1 so that the light of the lamp 12 is emitted through the light transmitting plate 11. In FIG. 3,
Reference numeral 5 denotes a lighting component storage box that stores a ballast and the like.

[0003]

However, according to the above-mentioned conventional structure, since the light of the lamp 12 enters from the surface of the light transmitting plate 11, the surface of the light transmitting plate 11 shines.
1 is weak in the outer peripheral end face. An object of the present invention is to provide a lighting fixture in which the outer peripheral end face of the light-transmitting plate shines strongly.

[0004]

The lighting fixture of the present invention is:
A light-transmitting plate with a hole in the center and inserted into the hole of this light-transmitting plate
Place the lamp and the light-transmitting plate between the top and bottom
Upper and lower case members that cover the lamp
And

[0005]

According to the structure of the present invention, the light of the lamp is directed up and down.
A translucent plate outside the vicinity of the periphery of the hole held in the case member
From the exposed part, but place the lamp in the center of the translucent plate.
The lamp light has a hole because it is inserted into the hole provided.
By being incident from the inner peripheral end surface, the amount of light emitted from the outer peripheral end surface increases, and the way of light emission on the outer peripheral end surface of the light transmitting plate can be increased.

[0006]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a partial cross-sectional view showing a main structure of a lighting device according to an embodiment of the present invention, and FIG. 1 and 2, reference numeral 1 denotes a light-transmitting plate made of a glass plate or the like provided with a hole in the center, and 1a denotes a light-transmitting plate 1.
1b is an outer peripheral end surface of the light transmitting plate 1, 2 is a lamp,
6 is a socket of the lamp 2, 7 is a fixture body, 8 is an arm 3
(Refer to FIG. 3) This is a fixture of the instrument main body 7 attached above.

This luminaire is used for a garden staging light or the like as shown in FIG. 3 as in the conventional example, and has a lighting component storage box 5 for storing a ballast lamp on the ground 4. The translucent plate 1 is provided at the upper part instead of the translucent plate 11. In this luminaire, a light-transmitting plate 1 provided with a hole in the center is disposed between a fixture 8 on an arm 3 (see FIG. 3) and a device main body 7, and a lamp 2 is provided in a hole of the light-transmitting plate 1. Inserted.
The apparatus main body 7 and the fixture 8 move the light transmitting plate 1 near the periphery of the hole.
Upper and lower case members that hold and cover the periphery of the lamp 2.
The light of the lamp 2 is transmitted from the fixture body 7 and the fixture 8 to the outside.
The light emitted from the upper and lower surfaces of the exposed portion of the light transmitting plate 1
In addition, as shown by the arrow in FIG. 1, the light passes through the light transmitting plate 1 from the inner peripheral end face 1a provided with the hole and is emitted from the outer peripheral end face 1b. As an orientation characteristic of the lamp 2 itself, light is emitted in a direction perpendicular to the arrangement of the lamp 2. When this light is incident from the inner peripheral end surface 1a of the light transmitting plate 1, the amount of light emitted from the outer peripheral end surface 1b of the light transmitting plate 1 is increased, and the way of illuminating the outer peripheral end surface 1b of the light transmitting plate 1 is increased. Can be.

[0008]

According to the lighting device of the present invention, since the lamp is inserted into the hole provided in the center of the light-transmitting plate, the light of the lamp passes through the light-transmitting plate from the inner peripheral end face where the hole is provided, and the outer periphery thereof. The light is emitted to the end face. As described above, when light is incident from the inner peripheral end face of the light transmitting plate, the amount of light emitted from the outer peripheral end face is increased, and the way of light emission on the outer peripheral end face of the light transmitting plate can be increased.
